how to fix this program error?

here is the code

monitor = peripheral.wrap("back")
while true do
monitor.setCursorPos(2,2)
monitor.write("Storage:")
monitor.setCursorPos(2,3)
monitor.write( getEnergyStored(draconic_rf_storage) getMaxEnergyStored(draconic_rf_storage) )
sleep(0.1)
end

the problem is this line

monitor.write( getEnergyStored(draconic_rf_storage) getMaxEnergyStored(draconic_rf_storage) )

you need to combine the two results as strings you do this like so:

monitor.write( tostring(getEnergyStored(draconic_rf_storage)).."/"..tostring(getMaxEnergyStored(draconic_rf_storage)) ) 

tostring is a function which will convert the number that is returned by you other function to a string so that it can be printed to the monitor
.. combines two strings
"/" just some formatting in the string to separate the two values


another things to note, I'm fairly sure that you are using your draconic_rt_storage incorrectly, it should be more like a peripheral (like you did with the monitor)

what does that mean?
how to fix?

local engCell = peripheral.find("draconic_rf_storage")
local monitor = peripheral.wrap("back")
monitor.setCursorPos(2,2)
monitor.write("Storage:")
while true do
  monitor.setCursorPos(2,3)
  monitor.write( engCell.getEnergyStored().."/".. engCell.getMaxEnergyStored() )
  sleep(0.1)
end

You might want to clear the line, if the energy drops from full, you will still have digits left from previous writes.
Also, I would recommend sleeping for at least a second, no reason to update too quickly.

ok,thx
